San Diego  A woman convicted of a rape charge after she helped abduct and attack a younger rival in 2011, then left her naked on the side of a San Diego freeway, was sentenced Friday to 35 years to life in prison.

Catherine McCoy, 49, was convicted last month of rape by foreign object along with allegations of kidnapping and use of a deadly and dangerous weapon.

She was found guilty in a previous trial of kidnapping, assault and making a criminal threat, all stemming from the same incident. In that trial, the jury was unable to reach a verdict on the rape count, prompting a retrial on only that charge.

During the sentencing hearing, San Diego Superior Court Judge Jeffrey Fraser said McCoy had not shown any remorse for assaulting the victim and dumping her out of a vehicle. McCoy’s purpose, the judge said, “was to have power over (the victim), to have control over her, to humiliate her,” and he called the attack sadistic.

According to the trial testimony, McCoy was angry at the other woman, who was 21 at the time, because she had sex with McCoy’s boyfriend.

The woman testified in trial that on Aug. 18, 2011, she took a brief trip across the border to Mexico to buy heroin and returned to a house on Snowdrop Street in City Heights. She said she went to the house to pick up her belongings. While she was there, McCoy beckoned for her to go into the garage about 7:30 p.m.

The woman said McCoy threatened to kill her, then punched her in the face. A man who was with McCoy, Christopher Carrera, grabbed the woman by the hair and forced her into the back seat of a Ford Expedition.

McCoy climbed into a back seat while Carrera got behind the wheel. As he drove, McCoy beat the woman with a flashlight and a golf club, ordered her to remove her clothes, and then sexually assaulted her with the golf club.

Carrera stopped the SUV on state Route 125 north of state Route 54, pulled the victim out and beat her before abandoning her.

A passer-by saw the naked woman emerging from the bushes about 8:30 p.m. Several motorists stopped to help her.

U-T San Diego is not reporting the woman’s name because she is a victim in a sex case.

McCoy’s lawyer, Charles Adair, had said Friday that his client admitted to the beating and was remorseful, but she did not admit to the rape.

Deputy District Attorney George Modlin argued for a longer sentence of 39 years, eight months in prison because of “the viciousness and callousness of this case.”

The victim did not attend the hearing, but Modlin read a written statement from her mother, who had a few pointed words for the defendant.

“You appear to have no soul,” the mother said in the statement. “You are an evil person and I am glad you will not be able to hurt anyone else.”

Carrera pleaded guilty last year to felony charges related to the attack and assault charges stemming from an unrelated July 2011 incident in Old Town. He was sentenced to 16 years and eight months in prison.
